Shop MQ-7 Sensor Module, 4-Pack Carbon Monoxide Gas Detector with for ttl Output for DIY Electronics Projects online at a best price in 香港. B0H3VRZDXX
  • 4-Piece Sensor Module Set: Includes four identical MQ-7 carbon monoxide sensor modules, each built with tin dioxide (SnO2) sensing element for consistent CO detection performance multiple setups.
  • CO-Specific Sensitivity: Optimized to detect carbon monoxide with high responsiveness, leveraging temperature-cycling operation-low temp for CO sensing and high temp for sensor recovery-to maintain stable signal output in changing environments.
  • DC5V-Compatible Analog and Digital Outputs: Delivers both AO (0.1-4V analog voltage proportional to CO concentration) and DO (TTL-level digital 0/1) signals, enabling flexible integration with microcontrollers, alarm circuits, or industrial monitoring systems.
  • Compact PCB-Mount Design: Measures just 32 x 20 x 22 mm with LONGLASTING PC housing, for space-constrained installations in safety devices, lab prototypes, HVAC air monitors, or classroom electronics projects.
  • Low-Power Operation at DC5V: Draws only 150mA at 5V DC input, supporting energy-efficient continuous monitoring in battery-backed or USB-powered applications-check your project's voltage regulation before use.

“Ubuy Hong Kong is a game-changer. I was looking for a specific American brand that doesn't ship to Asia, and Ubuy had it in stock. The selection of global products is incredible. It saves me the hassle of using freight forwarders or asking friends to bring items over. The process was seamless from checkout to delivery”
